Desktop effects question (nVidia)

[Colin J Thomson - G6AVK]

Hi,

Out of curiosity, 
I am using rpmfusions Nvidia drivers but I can't get any of KDE's desktop 
effects to work, everything else seems fine. Is this a known problem? 

All was fine in F11, I've tried to search for some info but no luck so 
far.

Clean install - F12/KDE-4.3.4

Cheers

Colin
